Etymology
The word 'refiner' is built on the verb 'refine', which entered English in the 16th century from the French 'raffiner', itself derived from Latin. The Latin components are 're-', meaning "again," and 'finis', meaning "end, limit, or boundary." The original sense was to reduce something to its finest, purest, or most precise state by repeatedly pushing it to its limit—like purifying metal by removing all dross. The agent suffix '-er', of Germanic origin, was then appended to denote a person or device that performs this action. Thus, a refiner is literally "one who makes something fine again," evolving from a literal processor of raw materials to also describe one who polishes manners or artistic style.
